せっかくの単体テストなんで、もっと from/to みたいな他の props の振る舞いとかもテストしても良いんですが、今回は E2E テストの廃止を目的としてるので、E2Eテストで書かれている観点の移植に集中してます。

it('value で指定した日付が選択されていること', () => {
render(<Calendar value={new Date(2020, 0, 15)} onSelectDate={vi.fn()} />)

expect(screen.queryByText('2020年1月')).toBeTruthy()
expect(screen.getByRole('button', { name: '15' }).getAttribute('aria-pressed')).toBe('true')
})

it('前の月に切り替えることができる', () => {
render(<Calendar value={new Date(2020, 1, 15)} onSelectDate={vi.fn()} />)

act(() => screen.getByRole('button', { name: '前の月へ' }).click())
expect(screen.queryByText('2020年1月')).toBeTruthy()

act(() => screen.getByRole('button', { name: '前の月へ' }).click())
expect(screen.queryByText('2019年12月')).toBeTruthy()
})

it('次の月に切り替えることができる', () => {
render(<Calendar value={new Date(2020, 10, 15)} onSelectDate={vi.fn()} />)

act(() => screen.getByRole('button', { name: '次の月へ' }).click())
expect(screen.queryByText('2020年12月')).toBeTruthy()

act(() => screen.getByRole('button', { name: '次の月へ' }).click())
expect(screen.queryByText('2021年1月')).toBeTruthy()
})

it('年を切り替えることができる', () => {
render(<Calendar value={new Date(2020, 10, 15)} onSelectDate={vi.fn()} />)

act(() => screen.getByRole('button', { name: '年を選択する' }).click())
act(() => screen.getByRole('button', { name: '2024' }).click())
expect(screen.queryByText('2024年11月')).toBeTruthy()
})

it('日にちを選択すると、onSelectDate が発火すること', () => {
const onSelectDate = vi.fn()
render(<Calendar value={new Date(2021, 8, 20)} onSelectDate={onSelectDate} />)
act(() => screen.getByRole('button', { name: '10' }).click())
expect(onSelectDate).toHaveBeenCalledWith(expect.anything(), new Date(2021, 8, 10))
})
})
